1 John, the sixty-second book of the Bible, is a pastoral circular that grounds believers in assurance of eternal life. It confronts false claims and denial of Christ's true humanity, insisting that genuine fellowship with God is seen in walking in the light, confessing sin, keeping God's commands, and loving one another.
The letter weaves three recurring tests—doctrinal truth about Jesus, moral obedience, and brotherly love—to distinguish the children of God from deceivers.
Chapters of 1 John
What is 1 John about?
The elder opens by testifying to what was from the beginning—the Word of life heard, seen, and touched—so that readers share fellowship with the Father and His Son. God is light; therefore believers walk in the light, confess sins, and trust Jesus Christ the righteous advocate and atoning sacrifice.
Those who truly know God keep His commandments and abide in Him. A new yet old command—love—marks the community, while love for the world's desires is rejected. Many antichrists have gone out, denying that Jesus is the Christ come in the flesh; the anointing teaches believers to remain in the Son and in the Father.
As God's children, believers practice righteousness and turn from sin; love is active and sacrificial, modeled on Christ who laid down His life. Spirits must be tested; confessing Jesus Christ come in the flesh distinguishes the Spirit of truth from error. God is love; those who abide in love abide in God, and perfected love casts out fear. The letter closes by affirming faith that conquers the world, heavenly testimony about the Son, confidence in prayer, and keeping from idols.
